Searching for Day of Week string, I was surprised that it is not built into Rules 5.1. So far I have avoided having to do anything outside of 5.1. I may have taken some extra steps, but I wanted to make things clear to anyone using this code. See screen shots below. [Screenshot (104)] [Screens…

Thanks for your cleanup. I did not see the "%" operator in the list. In that I plan to use DOW and Day_Of_Week in other places, I choose to keep things in what seems logical to me. Here is what I came up with: Set dtToday to current date(2025-12-21) Set Epoch to epoch time (dtToday) Set DOW to (…

In the spirit of consolidation without obfuscation, I offer this somewhat condensed version of the OP rule, which seems to work: [image] The variable Now is of DateTime, while DOW is a number and Days is a String as follows: [image]

The above info and solutions are great/clever--well done! As an FYI/alternative, here's another approach including a short day string that I use: [image]

You don't show where the variable "Day" comes from.

I defined it as a global. The condition is built in. I define many other globals like this that I treat as essentially system global vars (that as others have implied would ideally already be there): day, shortDay, month, year, etc.
